ford whoops.... my bad. COBRA OWNERS NEED TO READ!!


found this figured it might help some out


so every one knows 99-04 cobras have irs. well ford made an uh oh with some of the bolts that connect the suspension to the frame. im sure some of you know this but im also sure some of you dont because i recently found it out. basicly the forward irs bolts are the wrong size for the bushing hole....12mm. the correct size for this hole is 14mm. this missized bolt as you can immagion allows for the entire rear suspension to move and "slap arround". it is felt inside the car as a heavy clunk or jolt as the car engages in a gear or accelerates or decels. the correct size bolts can be found here:

Ford Racing 14mm IRS Subframe Front Mounting Bolt for 99-04 Cobras - FMS-M14-109BOLT
Ford Racing IRS Subframe Front Mounting Nut for 99-04 Ford Cobra - FMS-M14NUT

you will need 2 of each to do the job.

it took like 2 weeks for me to get them but it was worth it. i had the bolts installed in a shop for $20 under the table to the mechanic.... i would recomend doing this because the new bolt is the EXACT size of the hole and that meens that the holes need to be lined up perfictly. i can not imagion doing this on the ground because they had a big ass pry bar that would not fit underjack stands. it took about 30 min to install and most of my suspension noise was gone. i say most because my car has 96,000 mi on it and im sure the bushings are soft from moving so much and being rubber and all. all in all this fix was well worth it!

instead of a straight axle, like a ford 9 inch, instead, it allows the cars rear wheels to react to the road independently, making the car handle better. 99-04 cobras came with this.

03-9-5 SUSPENSION - CLUNK OR POP NOISE FROM REAR SUSPENSION - MUSTANG COBRA ONLY - SERVICE TIPS
NOISE - CLUNK OR POP NOISE FROM REAR SUSPENSION - MUSTANG COBRA ONLY - SERVICE TIPS

Publication Date: April 29, 2003

FORD: 1999-2003 MUSTANG


ISSUE:
Some 1999-2003 Mustang Cobra vehicles may exhibit a "popping" type noise while turning into or out of an incline, such as turning into a driveway, at low speeds (below 15 mph (25 km/h). The steeper the incline the more noticeable the noise will be. This may be caused by the lateral movement of the stabilizer bar or one or more of the fasteners shown in Figures 1-3, that may not be tightened within the required torque specifications.

ACTION:
Inspect and torque all of the fasteners listed for the proper torque. Refer to the following Service Information for details.

SERVICE INFORMATION

Raise vehicle on hoist and verify torque at the following components and locations:

Stabilizer bar bracket bolts (both sides) (Figure 1) - 42.8 3.7 Lb-ft. (58 5 N-m)
Stabilizer bar collar bolts (both sides) (Figure 1) - 6.6 1.0 Lb-ft. (9 1.4 N-m)
Lower shock bolts (both sides) (Figure 2) - 98.1 14.8 Lb-ft. (133 20 N-m)
Upper control arm bushing bolts (both sides) (Figure 3) - 66.4 10.0 Lb-ft. (90 13.5 N-m)
